Question 18 2 pts Jupiter is about 300 times the mass of the Earth and about 5 times as far from the Sun as the Earth. How does the gravitational force between the Sun and Jupiter compare to that between the Sun and Earth? O The gravitational force between the Sun and Jupiter is about 1/6 times that between the Earth and Sun. O The gravitational force between the Sun and Jupiter is about 60 times that between the Earth and Sun. The gravitational force between the Sun and Jupiter is about 12 times that between the Earth and Sun. O The gravitational force between the Sun and Jupiter is about 6 times that between the Earth and Sun.

Question 5 A large cannon is loaded with a relatively small cannonball, initially at rest. The cannonball is fired with a forward momentum of 500 N-s. What is the momentum of the cannon immediately after the cannonball is fired? OONS 1000 N-s in the reverse direction O 500 N-s in the reverse direction O 500 N-s in the forward direction 2 pts

Question 25 2 pts Richard Branson recently took a commercial vehicle into space. For a short period of time he and the other passengers were weightless. How is this possible? They were falling towards the Earth at the same rate as the spaceship. O Their mass in space was much smaller than on Earth. O They were far enough away from Earth to be free of its gravity. They were in a rotating spaceship which canceled, the effect gravity.
